Initialize mStatusView in LocationBarPhone if SEL is enabled

When launching into an incognito tab initially, the status view wouldn't
be initialized, and absent a search engine change, would never
be initialized ever again. This caused populateFadeAnimations to hide
everything in the location bar by accident, since the first visible
focused view was null.

We should always initialize mStatusView if the search engine logo
feature is enabled, and it is safe to do so; there guards against using
its padding etc. when not actually showing the logo.
